Question

Jab ham normal AC chalate hai toh hamein usme temperature low karna padta hai taki cooling ho...but jab ham car AC chalate hai toh hamein uska temperature increase karna padhta hai for cooling...why is it so?

Answer 1

Its not about the temperature when we turn on AC in cars.There is a scale residing between two colors. We switch from normal to red or blue for degree of cooling or warmth we want. Red is for cold and blue is for warm. So if we are turning it towards increasing value so we are actually decreasing the temperature of the car as like in normal room air conditioners.
